Holburt, Chief Engineer <br />Colorado River Board of California <br /> <br />INTRODUCTION <br /> <br />The drainage basin of the Colorado River covers an a~e~ ~- <br />244,000 square miles, which is approxirrately one-twelfth 0: ~~s <br /> <br />coterminous United States. It drains portions of seven st~te5 anj <br /> <br />the Republic of Mexico. The Colorado River Compact, signee t:,- repre.- <br /> <br />sentatives of the Basin States in 1922, divided the use 0: t~e waters <br /> <br />of the river between the Upper and Lower Basins, with the i~~~5ion <br /> <br />point being Lee Ferry, Arizona. The Upper Basin is composei ;~imarily <br />of the States of Colorado, New Mexico, Utah and Wyoming. ~~e Lower <br />Basin is composed primarily of the States of Arizona, Ca1~:2~,ia, <br />and Nevada. <br /> <br />Historically, the Colorado River has carried a large ~~ss:lved <br /> <br />mineral load resulting in salinity concentrations higher ::,s:: :hat <br /> <br />of most other majo:::' rivers. In its natural state, before :::5 edvent <br /> <br />of modern man, the river's salinity is estimated to have ::ee:: epproxi- <br /> <br /> <br />mately 250 rug/I at Lee Ferry, Arizona, which is located se':e:::se'n miles <br /> <br />*Presented onCh~ 29. ~at the 1982 National Spring :::-_':C'::'~ion <br />of the American Society of Civil Engineers. <br />
